The summer of 1760 was dreadfully hot in Pennsylvania; and the thunder gusts frequent and terrible. Several ships at the wharves were struck and greatly injured. One of them in particular, a very large ship, had her mainmast torn to pieces, and her captain and three seamen killed. Of houses, both in town and country, many were struck; and some of them, as barns with large quantities of hay, and warehouses with hemp, were set on fire and destroyed to the great detriment and terror, both of the unfortunate sufferers and their neighbours. These things, though melancholy in themselves, were not without their good effects. They served to place in the strongest point of view, the admirable efficacy of the newly invented lightening rods. For, while buildings destitute of them, were often struck, and sometimes with great loss of lives and property, those houses that had them, were hardly ever known to be hurt, though the neighbours who saw the dismal clouds when they bursted, with such hideous peals of thunder and streams of lightning, were sickened with horrid apprehension that all was lost. And even the house keepers themselves, when recovered from their terrors and faintings, would fly shrieking from chamber to chamber, amidst the clouds of sulphur to see who were _dead_. But behold, to the delicious wonder of themselves and congratulating friends, all were safe. But still the cry was, _certainly the house was struck! the house was surely struck! let us examine the conductors_. The conductors were resorted to and examined, and behold! the wondrous laws imposed of God on the most powerful of his creatures! The furious lightnings had fallen on the houses in torrents of fire, threatening a wide destruction. But the iron rods, faithful to their trust, had arrested the impending bolts, and borne them in safety to the ground. But it was found that the cataracts of lightning had proved too powerful for the rods; in some instances melting them in two at their slenderest parts, and in others entirely consuming them into smoke. But though these GUARDIAN RODS had perished in their conflict with the rude lightnings, yet they had succeeded in parrying the dreadful stroke with perfect safety to the buildings and their terrified inhabitants; thus impressing all men with joy and thankfulness, _that God had given such complete victory over one of the most terrible of all our natural enemies_. In short, to use the handsome language of president Adams, "nothing perhaps that ever occurred on earth, could have better tended to confer universal celebrity on man, than did these lightning rods of doctor Franklin's. The idea was certainly one of the most sublime ever suggested to the human imagination. That mortal man should thus be taught to disarm the clouds of heaven, and almost snatch from his hand '_the sceptre and the rod_!'"
